Meta Information
ID:choline
Name:
Schema Version:AIM-2.0
Interactions
Target id:
/condition/pregnancy
Target name:
Pregnancy
Severity:
major
Interaction type:
requirement
Nature:
absolute
Description:
Choline requirements increase significantly during pregnancy for proper fetal brain and neural tube development. Inadequate intake is common and supplementation is often recommended to support the health of both mother and child.
Actionable advice:
Ensure adequate choline intake through diet and/or supplements during pregnancy, as advised by your doctor.
Target id:
/condition/lactation
Target name:
Breastfeeding (Lactation)
Severity:
major
Interaction type:
requirement
Nature:
absolute
Description:
Large amounts of choline are transferred into breast milk to support infant development, dramatically increasing maternal needs. Supplementation may be necessary to avoid maternal depletion and ensure sufficient supply for the infant.
Actionable advice:
Maintain high choline intake while breastfeeding to support both your health and your baby's development.
Target id:
/class/anticholinergic-medications
Target name:
Anticholinergic Medications
Severity:
moderate
Interaction type:
diminishing
Nature:
absolute
Description:
Anticholinergic drugs (e.g., for overactive bladder, some older antihistamines) work by blocking acetylcholine, while choline is a precursor used to create acetylcholine. Taking them together may reduce the effectiveness of the anticholinergic medication.
Actionable advice:
Consult your doctor before combining choline with anticholinergic drugs as it may oppose their intended effect.
Target id:
/class/cholinesterase-inhibitors
Target name:
Cholinesterase Inhibitors
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Description:
Both choline and cholinesterase inhibitors (e.g., donepezil for Alzheimer's, Huperzine A) increase acetylcholine levels. Combining them can lead to an excessive cholinergic effect, causing side effects like nausea, diarrhea, and slowed heart rate.
Actionable advice:
Avoid taking high-dose choline with cholinesterase inhibitors unless directed by a physician.
Target id:
/intervention/l-carnitine
Target name:
L-Carnitine
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Description:
Gut bacteria can convert both choline and L-carnitine into TMA, which is then converted to TMAO in the liver. High doses of both supplements taken together may significantly elevate TMAO, a metabolite linked to cardiovascular risk.
Actionable advice:
Avoid taking high doses of choline and L-carnitine concurrently; consider alternating them if both are needed.
Target id:
/intervention/methotrexate
Target name:
Methotrexate
Severity:
moderate
Interaction type:
requirement
Nature:
absolute
Description:
Methotrexate, a drug for cancer and autoimmune disease, can impair the body's own production of choline, thereby increasing the dietary requirement for it to prevent deficiency and potential liver toxicity.
Actionable advice:
If taking methotrexate, discuss with your doctor whether choline supplementation is necessary.
Target id:
/intervention/vegan-diet
Target name:
Vegan Diet
Severity:
moderate
Interaction type:
requirement
Nature:
absolute
Description:
Vegan diets lack major dietary sources of choline such as eggs, beef, and fish, increasing the risk of inadequacy and raising the need for targeted food choices or supplementation.
Actionable advice:
If following a vegan diet, consider regular choline supplementation to meet daily requirements.
Target id:
/condition/renal-impairment
Target name:
Renal Impairment
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Description:
The kidneys are responsible for clearing choline metabolites like TMAO. In individuals with poor kidney function, high-dose choline supplementation can lead to the accumulation of these metabolites and a pronounced fishy body odor.
Actionable advice:
Consult a physician before using choline supplements if you have kidney disease.
Target id:
/condition/pemt-mthfr-polymorphism
Target name:
PEMT or MTHFR Genetic Variants
Severity:
moderate
Interaction type:
requirement
Nature:
absolute
Description:
Common genetic variations in the PEMT or MTHFR genes can impair the body's ability to produce or utilize choline and related nutrients, increasing the dietary requirement.
Actionable advice:
If you have known PEMT or MTHFR variants, you may require a higher choline intake; consult a knowledgeable practitioner.
Target id:
/condition/fatty-liver-disease
Target name:
Non-alcoholic Fatty Liver Disease (NAFLD)
Severity:
moderate
Interaction type:
synergistic
Nature:
absolute
Description:
Choline is essential for packaging and transporting fat out of the liver. A deficiency can contribute to fat accumulation, and supplementation may support liver health in NAFLD.
Actionable advice:
Ensure adequate choline intake as part of a comprehensive plan to manage fatty liver disease.
Target id:
/intervention/folate
Target name:
Folate (Vitamin B9)
Severity:
moderate
Interaction type:
synergistic
Nature:
absolute
Description:
Choline and folate are metabolically linked in the one-carbon cycle. Adequate levels of one can help compensate for a mild deficiency in the other, and together they support healthy homocysteine levels.
Actionable advice:
Ensure adequate folate intake when supplementing with choline for optimal metabolic function.
Target id:
/intervention/vitamin-b12
Target name:
Vitamin B12
Severity:
moderate
Interaction type:
synergistic
Nature:
absolute
Description:
Vitamin B12 is a critical cofactor in the metabolic pathway that links choline and folate metabolism. A deficiency in B12 can impair this cycle and increase the need for choline.
Actionable advice:
Maintain adequate Vitamin B12 status for choline to be utilized effectively in methylation pathways.
Target id:
/intervention/betaine
Target name:
Betaine (TMG)
Severity:
moderate
Interaction type:
synergistic
Nature:
absolute
Description:
Betaine is a metabolite of choline and both can donate methyl groups to lower homocysteine. They work together, and adequate betaine can spare the body's choline stores from being used for this purpose.
Actionable advice:
Betaine (TMG) and choline can be taken together to support methylation and cardiovascular health.
Target id:
/biomarker/homocysteine
Target name:
Elevated Homocysteine
Severity:
moderate
Interaction type:
synergistic
Nature:
absolute
Description:
Choline, primarily through its conversion to betaine, plays a key role in converting potentially harmful homocysteine back into methionine, thus helping to lower elevated levels.
Actionable advice:
Choline supplementation can be an effective strategy for helping to manage high homocysteine levels.
Target id:
/class/choline-precursors
Target name:
Other Choline Forms (Alpha-GPC, Citicoline)
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Description:
Alpha-GPC and Citicoline are potent sources of choline. Combining them with other choline supplements increases the total choline load, raising the risk of cholinergic side effects like headaches, GI upset, or a fishy body odor.
Actionable advice:
Use only one form of choline supplement at a time to avoid excessive intake.
Target id:
/dietary/meal
Target name:
Any Caloric Meal
Severity:
minor
Interaction type:
synergistic
Nature:
temporal
Temporal spacing:
Hours before target:
0
Hours after target:
0
Description:
Taking choline with food, particularly a meal containing some fat, can improve its absorption and reduce the likelihood of gastrointestinal side effects.
Actionable advice:
Take choline supplements with a meal.
Target id:
/condition/bipolar-disorder
Target name:
Bipolar Disorder
Severity:
minor
Interaction type:
adverse
Nature:
absolute
Description:
While high-dose choline has been studied for mania, increasing acetylcholine levels could theoretically worsen depressive symptoms in some individuals with bipolar disorder.
Actionable advice:
Use choline supplements with caution and under medical supervision if you have bipolar disorder.
Target id:
/condition/major-depressive-disorder
Target name:
Major Depressive Disorder
Severity:
minor
Interaction type:
adverse
Nature:
absolute
Description:
There is a theoretical concern that increasing acetylcholine levels with choline supplementation could exacerbate symptoms in some individuals with depression. The evidence is not strong but warrants caution.
Actionable advice:
If you have depression, discuss choline supplementation with your doctor before starting.
